ADOLF BELER, OF PITTSBURGH, PENNSYLVANIA, 'ASSIGNOR T0 BELER WATER HEATER CO., OF PITTSBURGH, PENNSYLVANIA.

INSTANTANEOUS GAS HOT-WATER HEATER.

To all whomt may concern Be it known that I, Anonu BELER, a citizen of the United States, residing at. Pittsburgh, in the county of Allegheny and State. of Pennsylvania, have invented a new and useful Instantaneous Gas Hotater Heater, of which the following is a specification.

The present invention relates to improvements in instantaneous gas hot water heaters, the primary object of the invention being the provision of a novel form of water pressure actuated mechanism to automati cally and simultaneously control the gas flow with the turning on and off of the water supply, in combination with a thermostatically controlled device for automatically cutting off or decreasing the flow of gas, due to the too high temperature of the Water within the heater.

A further object of the present invention is the provision of a pressure actuated device operably connected with a water supply, whereby the Water is permitted to gradually expand a plurality of scaled diaphragms or expansible disk chambers to finally actuate a main valve or valves, to permit the water to flow at the full pressure to the heater, and to simultaneously actuate a gas flow control valve, thereby producing an instantaneous heater of an etficient and practical char acter.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed Without departing from the spirit of the invention.

In the drawings: Figure 1 is a front elevation of a heater with the combined water actuated and thermostatically controlled devices in elevation and operable relation to the water and gas pipes. Fig. 2 is an enlarged section through the water actuated mechanism and its casing, dotted lines illustrating the posit-ion of the parts when expanded. Figs. 3, 4 and 5 are detail views of parts of said water actuated mechanism. Fig. 6 is a longitudinal section of a modified form of water actuated mechanism. Fig. 7 is a end view thereof. Fig. 8 is a perspective view of the valve shown therein.

Specification of Letters Patent.

vApplication filed September 11, 1911.

Patented. May 7,1912. Serial No. 648,724.

Fig. 9 is a section through both of the gas controlled valves and the thermostat.

Referring to the drawings, the numeral 1 designates the vertically disposed gas conduit or pipe, having connected therein the thern'iostatically controlled gas valve 2. which normally opened, and is controlled by the thermostatic regulator device 3, the detail construction of which is shown in ap plicants Patent No. 917,701, dated April 6th, 1909, and will therefore not be described in detail herein. The casing 3 is properly connected to receive the hot water from the coil (not shown) of the heater H, while the water controlled casing 5, is disposed between the cold water supply pipe 6, which enters the nipple 7, of the removable cap 8, of the casing 5, and the pipe 9, which is connected to the nipple 10, of the casing 5 to the coil (not shown) of the heater. Disposed to seal the annularly shouldered end 11, of the casing 5, is a disk 12, which is normally held tightly in the end 11 by the cap 8, said disk having concentrically therethrough an aperture 13, while upon the inwhich is connected the nipple 15, of a series of expansible diaphragms or disk chambers 16. Connected concentrically to the wall 16 of the extreme inner chamber 16, and extending concentrically through all of the chambers 16 and the aperture 13 of the disk 12, is a stem 17, whose outer threaded end 18, is connected concentrically to the disk or plate 19, which is normally held outwardly within the chamber 20, of the cap 8, by the compressible action of the chambers 16, due to the equilibrium, or the static condition of the water within said chambers 16. This plate 19, has attached thereto and projecting toward and through the valve ports 22 of the disk 12, a plurality of valve stems 21, which are tri-angular in cross-section for a greater'portion of their length, terminating in the cylindrical valves 23, which are of sufiicient size to fit snugly within to close or seal the respective ports 22. This is the normal position of the said valves.

In operation, when it is desired to instantly heat the water in theheater H, and also supply water thereto concurrently with such heating, the cock or faucet (not shown) is operated to permit water to. flow into the chamber 20, of the cap 8. The water will then slowly pass through the apertures or bores a, about the aperture 13 in the disk 12,

into thechambers 16. Such action gradually expands the chambers 16, and pull inwardly upon the stem 17, which in turn pulls inwardly the disk 19 and all of its" shown) of the heater H. The bores or apertures a form the means of communication between the chamber 20 and the expansible chambers 16. Simultaneously with this action, the socketed boss 25, disposed exteriorly and concentrically of the wall 16 of the extreme inner chamber 16, will be moved into contact with the inner end of the glass non-corrodible stem or rod 26, which is mounted in the concentric stufling box 27, of the casing 5. The stem or rod 26, is thus moved outwardly and engages the stem 28, of the gas supply control valve A, the detail structure of which forms no part of this application, but is the subject matter of an application filed June 25, 1910, Serial No. 568,876; and by this means automatically and simultaneously with the turning on or of the flow or feed of water to the heater, gradually increases the gas flow and the flame at the burner (not shown).

In the modified form of water actuated mechanism, as shown in Figs. 6 and 7, the disk 19, is dispensed with, the plate 12, be,- ing provided with a pair of lugs 29, which have journaled therein the lever 30, which is provided with a valve-31,'which normally han s to close the valve port 32, of the disk p ate 12'. This lever is provided with an aperture 33, through which the stem 17,

passes, and is provided with an adjustable circular head 34, which as the chambers 16', are expanded in a similar manner to the chambers 16, pulls the "stem or rod 17', to cause the head 34 to engage the shoulder 35 of the upper end of the lever 30, tilting said lever to remove the valve 31 from over the the heater.

port 32, and permit the water to enter the casing 5, and finally the coil (not shown) of The expansible chambers 16' are in communication with the chamber 20, through the apertures or bores a, similarly to that shown in Fig. 2.
